to that I, GEORGE A. JOHNSON, i the United States, residing in the county of Cook and State have invented a new and useful nt in Steel Platforms for Rail- 1f which the following is a specifi* ntion relates to improvements in rms for railway passenger cars. of my invention is to provide 'lnproved steel platform construcenerally on passenger cars, which n aking the longitudinal beams of cross section, made from either l rolled steel, said beams having per edges outwardly turned in- 1med securing flanges.

i tion further consists in providfl ing plates at the ends of the j new and improved construction, rmore in providing a new form "y to be used in the beams at the L.. the stop-castings are attached which filler blocks are also proi means for preventing longitudiement of the same relative to the ers of the car platform.

tion further consists in the novel l of parts and devices and in the inations of parts and devices herenddescribed and more particuil ed in the claims.

Fig. 12 is a transverse section, taken on the line 12-12 of Fig. 13. Fig. 13 is a longitudinal section of the structure shown in Fig. 11, taken on the line 13-13 of Fig. 11. Fig. 14 is an enlarged, longitudinal section, showing another form of stop castings as applied to the U shaped beams. l Fig. 15 is a top plan view of the structure shown in Fig. 14. Fig. 16 is a transverse section, taken on the line 16-16 of Fig. 14.

In the drawings, 20 represents the floor of a passenger car platform structure, 21 the cross sills, each having on their lower face, preferably, a steel wearing plate 22.

23 denotes the end sill, 24 the vestibule end sill, 25 the buffer plate and 26 the buffer stem.

As shown in the drawings, I prefer to use four parallel U shaped metal beams, the inner pair 27 of which are longer than the outer` pair 28. Each of these U shaped beams preferably consists of a bottom portion 29, side portions 30 and outwardly turned securing flanges 31 at the upper edges of the side portions 30. These beams are secured to the cross sills by means of sill bolts 32 which extend through the bottom portion 29 of each of the beams, and in some places where tie-plates 33 are used, through the tieplates and the U shaped members. To more firmly secure the members in position, there is provided at the end of the platform proper an angle plate 34 secured to the U shaped members 27 and 28 by rivets 35 extending through the angle plate and the securing flanges of the beams. An additional tie-plate or brace member 36 is provided under the vestibule plat-form and is secured to the members 27 and 28 by rivets 37, passing through the lower portion 29 of each of the -U shaped members. In order to prevent longitudinal movement of the beams due to any pull or pushing action transmitted to the same, I provide each of the members 27 and 28 with anchoring plates 38. As more clearly shown in Figs. 5, 6 and 7, these anchoring plates 38 consist of a horizontal .portion 39, extending across both of the sei curing anges-of each of the U shaped members and hook portions 40 formed integral with the portion 39 and adapted to fit over and slide on the securing flanges 31 of the beam. These anchoring plates I place immediately adjacent and on each side of, the steel plates 22 on the lower portion of the cross sills 21. Each of the anchoring plates 38 is securely fastened to the beams by rivets 41.

Instead of using the plates 38, I may use the structure shown in Figs. 8, 9 and 10, in which I slit the flange portions 31 of the beams at points 42 spaced apart equal 'to 'the width of thevcross sill, and turn such slotted portions 43 of the fiange at each side of the cross sill upwardly and thus form an anchoring means integral with the beams.

Those portions of the securing flanges 31 immediately beneath the cross sills are secured to the cross sills by means of rivets or bolts. The intermediate members 27have attached thereto draft rigging stop-castings 44 secured thereto by rivets 45 and 46, the latter passing through angle portions 47 of the stop castings 44 and the lower portions 29 of the members 27. The rivets 45 pass transversely through each of the side portions 30 of the beams 27 and through a filler block 48 located in each of the U shaped members 27. As more particularly shown in Figs. 11, 12 and 13, these filler blocks 48 each comprises two parallel, vertical side portions 49, connected by a plurality of transverse, cylindrical, cored hubs 50, these hubs being suitably spaced so as to coincide with the rivetholes in the stop castings 44, the rivets being adapted to pass therethrough. The side members 49 each consists of a lower, horizontal portion 51 and an upper portion 52 parallel to, but ofi'- set from, the portion 51. Each of the portions 52 is provided with a cut out recess 53 adapted to closely fit the cross sill 21. In this manner I provide means for preventing' the longitudinal displacement of the filler blocks 48 and thus make a solid structure to which the stop castings may be secured.

In Figs. 14, 15 and 16 is shown another form of stop castings 54, each of which is provided at its forward upper edge with an abutment 55 through which the st-rain on the stop castings is transmitted to the end sill 23. In this particular structure the filler blocks 56 do not have the anchoring means shown on the filler blocks 48. But the beams 27 are provided with anchoring plates 38 on the rear side of the adjacent cross-sill.

Various changes may be made in the details of construct-ion of my improved steel platform, and I do not wish to be limited to the exact details shown in the drawings, eX- cept as defined in the claims.
